After switching to Scala 2.10 I get tons of warnings:
reflective access of structural type member method ... should be enabled by making the implicit value language.reflectiveCalls visible
What does it mean?
The warning actually tells where to look in the documentation for an explanation:
Test.scala:9: warning: reflective access of structural type member method y should be enabled
by making the implicit value language.reflectiveCalls visible.
This can be achieved by adding the import clause 'import scala.language.reflectiveCalls'
or by setting the compiler option -language:reflectiveCalls.
See the Scala docs for value scala.language.reflectiveCalls for a discussion
why the feature should be explicitly enabled.
